Hi marinofret,

As Fretsource said, you already know the majors if you know the minors. It just comes down to knowing the locations of the tonics for the scales. Take the typical A minor pentatonic at the 5th fret that everyone learns. If you play that same scale but consider the note C at the 8th fret as the tonic you know have a C major pentatonic scale.

You do not have to learn a new fingering, just start and stop the scale in a different place. Try it and listen to the difference in tonality. Start from the A and play the scale up and down and stop on the A. Then leave off the A and start on the C and play the scale up and down. Even though they are the same notes changing the start and stop point shifts the tonality.

The difference in application comes down to how you think about the scales. Thinking in major vs. minor can lead to different uses of the scale. This is a big topic. In the end it still always gets down to how the scales relate to the chords you are playing over and centering your lines around the chord tones. That's why many players like the pentatonic scales. They are mainly comprised of chord tones with a couple of color tones thrown in.

Best Wishes,

Bob
